Airbus is to cut around 15,000 jobs across its global operations as a result of the coronavirus crisis.
The figure includes 900 positions already earmarked in Germany.
The company said its future was at stake after the Covid-19 pandemic rocked the air travel industry.
Europe's biggest aerospace group said it would cut some 5,000 positions in France, 5,100 in Germany, 900 in Spain, 1,700 in the UK and 1,300 elsewhere for a core total of 14,000.
Additionally, the company has already agreed to shed 900 jobs at its Premium AEROTEC unit in Germany.
The move is subject to talks with unions which immediately renewed pledges to oppose compulsory redundancies.
Airbus has refused to rule them out as it seeks voluntary departures, early retirements and long-term partial employment schemes.
Airbus said it wanted a deal on the job cuts by 2021.
"It's going to be a mighty battle to save jobs," said Francoise Vallin of the CFE-CGC union.
A French finance ministry official said the government expected Airbus to use instruments it had made available to reduce job cut numbers.
On 3 June, Reuters reported that Airbus's reduced production targets pointed on paper to cuts of 14,000 full-time posts.
Earlier today, French union sources predicted a headline figure of 15,000 and pledged to fight compulsory cuts.
Airbus has a 135,000-strong workforce, heavily populated by veterans of its original A320 development. About 37% of staff are due to retire this decade.
The hard-left Force Ouvriere union and others said they would oppose any mandatory cuts.
Exceptional secrecy had surrounded the politically sensitive restructuring affecting jobs in Britain, France, Germany and Spain, the company's key backers in a fierce contest with US rival Boeing for orders and industrial clout.
Airbus is expected to juggle its response to the industry's worst crisis with pressure to keep cuts to a minimum after France and Germany announced plans to support aerospace.
Michel Pierre, representing the CFDT union at Airbus, said the company had refused direct state intervention in its capital,upholding corporate governance reforms in 2013.
Compulsory sackings would therefore be "totally unacceptable," he said.
Industry sources say Airbus is basing the restructuring on a 40% drop in underlying aircraft production for two years.
The company's programmes chief, meanwhile, said it was slowing a push into high-margin services as a result of a slumpin air travel but maintaining its diversification strategy.
Some industry sources say Airbus has all but abandoned a goal of more than doubling services revenue to $10 billion this decade and transferred some staff to other roles.
